SPECIFICATION forming part of Letters Patent No. 352,999, dated November23, 1886.

Applicatioulled July 19, 1886. Serial No. 208,472. (No model.)

To aZZ whom, it may concern: y Beit known that I, WILLIAM S. PATEs, ofAlton, in the county of Madison and State of Illinois, formerly ofJonesborg, in the county of Montgomery and State of Missouri, a citizenof the United States, have invented a certain new and useful Improvementin Sulky- Flows, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification, and in which- Figure lis a longitudinalvertical section showing the plow proper in a depressed position. Theelevated position of the plowis indicated by broken lines, the changedpositionv of the handlever and connections being indicated in the samemanner. larged perspective detail view. Fig. 3 is a perspective view ofthe bracket by which the axle and tongue are secured together, and towhich the rock-bar and one arm of the lifting-bail are fulcrumed; andFig. 4 is a perspective view of the fulcrum-bracket to which the otherarm of the lifting-bail is fulcrumed. Fig. '5 is a detail horizontalsection through one of the fulcrum-joints of the lifting-bail, showingthe double function of the tubular studs on the brackets as sleeves tothe pivotl bolts that secure the bail and forming the bearing lon whichthe bail works and is fnlcrumed while lifting the beam. Fig. 6 is aperspective view of the saddle-bracket, show- .ing its elongated slotand corrugated frictionsurface for the adjustment and leveling of theplow. Fig.- 7 is a perspective view of one of the-corrugated washersthat engages on the friction-surface of the saddle-bracket and seats theset-screw Z, and Fig. 8 is a section showing the means of attachment ofthe saddlebracket to the bail.

My invention relates to improvements in sulky-plows, and especially toelevating, leveling, and adjusting devices in connection therewith; andmy invention consists in fea-` the lever.

Fig. 2 is an en.

C is the lever for operating the crank-axle for leveling the plow, andyD is the segmental rack for holding the lever C.

E is the spring-latch that works inA the box E and engages the teeth Dof the rack D. E2 is the rod that connects the latch with the pivotedtrigger E3, adjacent to the handle of The latch is projected int'o thenotches D2' of the rack by a spring, E4, behind the trigger, and holdsthe crankaxle in the position that the lever C has placed it, thusenabling the operator to level the plow and i lock its adjustment.

F represents the tongue, and F a curvilinear bar that braces the tongueto the axle, being secured to the tongue by a bolt, f, and to the axleby a bolt, 1o.4

G is a` segmental rack secured to the tongue by the bolt f and also by abolt, f2, for holding-the adjustment of the bellcrank lever H, that issecured to the tongue by a pivot-bolt, H2, passing the segmental plate.elevates, depresses, and adjusts the vertical position of the plow.

J are the teeth on said rack which have intervening notches,G2, betweenthem,into which notches the spring pawl or latch I, that-works in thebox I, js projected bythe trigger-spring I2, that throw's out thepivoted trigger I3 from the handle of the lever, and through itsconnecting-ro'd I4 springs the latch into its seat between the teeth ofthe rack and locks the vertical adjustment ofl the plow either in orcompletely lifted from the ground.

The lever H has a bell-crank arm, H. A link, J, is pivoted by a pin,j,at the lifting extremity of the short arm H of the bell-crank lever, andis also pivoted by a pin, j', within the bifurcated end K of the rockbar or lever K, which is pivoted on a sleeve, K, to the bracket N,secured by a horizontal bolt, k, passing through the sleeve K2 andthrough the tongue, vertical bolts n n passing through the tongue andhorizontal bolt n passing through the axle. The bracket N thus securesthe axle and tongue together, having angle-flanges at N and N 2 thatrelatively embrace the axle and the tongue, to which they are bolted.Within the fork K3 ofthe rear extremity of the lever K is pivoted by apin, k2, a pendent bifurcated bar, L, in the fork L of which is pivotedbya pin, Z, the inner arm, M', of the 1-shaped This lever IOOelevating-bail M,that lifts the plow-beam,and whose functions will befully described hereinafter.`

The axle end of the arm M ofthe lifting-bail has bearings around atubular stud, O, that projects from the bracket N. The stud embracesthedouble function of a sleeve to the bolt O,thatsecures the bail ltothe said bracket, and that of a fulcrum-bearing for one arm of 1o thebail, the other arm, M, being alike fulcrumed atits axle end on asimilar tubular stud, O2, on t-he other fulcrum-bracket, l?, throughwhich stud a bolt, O, passes and secures the attachment of that arm ofthe bail. The fulr 5 Crum-bracket l? has angle-fianges P', that embracethe axle to which they are bolted by the brace-bolt p.

Apendent rod, Q, is pivoted by a bolt, Q', to the rock bar or lever Kback of its pivoted 2O connection with the bracket N, and its lowerextremity passes through and works in a perlforation, R, in the arm R,that projects from the bottom of said bracket. A spiral pushspring, S,is secured around the pendent rod Q and projects against the bracket-armB at one extremity and the shoulder Q2 below the head of the pendent rodthat carries it at the other extremity. This spring pushes against theelevating end of the rock-lever sufficiently o in the rear of itspivoted attachment to the bracket to materially aid the operator inelevating the plow in and out of the ground, relieving the drag on thefurrow-tread, and giving also a lively reactionary movement to the 5 5plow, more fully pointed out hereinafter in the description of itsoperation.

The plow may be the ordinary plow, T, provided with the beam U.

A clip, V, formed with trunnion-pivots WV, lo is screw-clamped on thearch of the plow-beam, and can be adj usted bythe operator to balancethe suspension of the plow. The clip is provided with trunnions W', thatWork within the tubular lugs X X, which project from adjustl5 ablesaddle-brackets Y Y, that straddle the rear bar of the lifting-bail, towhich they are secured by screw-bolts Z Z. These saddlebrackets areprovided with elongated slots Y', through which the bolts Z'pass thatclamp :o them to the bail. A corrugated friction-surface, Y, is formedon the rear surface of the saddle-bracket, and a correspondingcorrugated washer, YS, engages in the corrugations of the bracket, andon its smooth side forms 5 5 the seat for the set-screw Z. i It will beunderstood that the rear bar of the bail and the washers are perforatedwith round holes, but the saddle-bracket has an elongated slot, Y',through which the bolt Z passes,which allows lo of vertical adjustmentto level the plow or nicely adj ust the angle at which it throws itsfurrow. When the screw-bolt or set-screw Z is'secured, the corrugationsin the washer lock the adjustment in the position the operator 5 5 hasplaced it.

The operation of my sulky-plow is as follows: The clip having beenadjusted on the beam to balance the plow and regulate its draft issecurely bolted thereto. Its trunnions have a free pivotal movementiuthelugs X of 7o the saddle-bracket that straddles the liftingbail, sothat as the operator elevates or lowers the plow the presentation ofthebeam will readily conform itself to the changed line of draft. Thelever H is then adjusted to lower the plow to the level of itsfurrow-tread, and the sp ring-latch engaging in the rack keeps it tothat adjustment until the operator changes the position of the lever. f

If it is desired to elevate the plow in or out 8o of the ground, it willbe seen that as the operator pulls the lever H toward him the pendentlink pivoted to the bell-crank of the lever depresses the front end ofthe rock-lever K, the spring at the same time pushes up on the 8 5 rearend of the lever, thereby assisting the operator to raise the plow. rlhespring also releases the heavy drag on the furrow-tread and gives alively reactive movement to the beam, that as the plow meetsobstructions that 9o it could not otherwise overcome will frequentlyenable it with a counter and divergent movement to pass around them.

It is evident that the plow can either be` raised to turn a shallowfurrow only, or raised completely out of the ground for removal fromfield to eld or traveling on the road.

By the use of a straight instead of an arched axle it is found toprovide a stiffer and better ballasted frame. It also gives theopportuico nity of working the plow-beam above the axle and provides afirm support for the fulcrumbrackets that support the lifting-bail. Afurther advantage of having the axle and liftingbail beneath theplow-beam is that there are no suspension-clips (on which the strain isfrequently very heavy, to break and cause expense and delay.

By the use of a straight axle instead of the usual arched axle the axleperforms the func- 11o tion of a grass-rod in breaking down all thelarge weeds ahead of the plow and enables the plow to turn a smoothfurrow in foul land where otherwise it would choke.

The free pivoted bearings for the plow in thelugs of thesaddle-brackets, that aresecured to the bail, allow the beam, andconsequently the plow, so much more freedom of movement that impedimentsin its progress are more readily surmounted or passed by its re- 12oactive divergent action, and especially in gravelly soil, the freedom ofmovement is found to result in a lighter draft.

v The crank-axle with its operative devices combine with other featuresin this invention to provide the means for leveling and adjusting theplow not only with regard to the depth of furrow but also to the angleat which it is cut and laid.

I claim as my invention- 13o 1. The combination, with the axle B, of thebrackets N and P, secured on the axle, the bail M, hinged to thebrackets, a plow having its beam extending over the bail and axle andhinged to the bail, and a lever and connections between the lever andthe bail for raising and lowering the plow, substantially as described.

2. The bracket N, formed with angle-anges N and N2, tubular studs orsleeves O and K, andthe arm R, substantially as described.

3. The combination, with the axle B and the tongue'F, ofthe bracket N,having angle-flange N on the axle and angle-flange N2 over the tongue,and the bolts n and n, by which 'the bracket is secured to the tongueand to the axle, respectively, substantially as described. 4. Thecombination,y with the axle B, brackets N and P, the bail M, and plowhaving its beam extending over the bail and axle, of the rock-lever K,hand-lever II, rod Q, pivoted to the rocklever and extending throughA anarm of the bracket N, and the spring surrounding the rod, substantiallyas described.

5. The combination, with the axle B, the

bail M, devices for raising andvlowering the bail, and a plow having itsbeam extending over the bail and axle, of the clip Y, secured to thebeam, having trunnions W, adjustable saddle-brackets Y on the rear barof the bail,

having corrugatedsurface Y2, tubular lugs K, and elongated slots Y',washers Ys, having corrugated surfaces, and the bolts Z, substantiallylas described.

6; The combination, in a sulky-plow, of the plow-beam extending over theaxle and hinged by saddle-brackets to a lifting-bail, the said bracketshaving elongated slots and a corrugated friction-surface and corrugatedwashers with set-screws, all arranged to adjust the attachment of thegang-beam to the bail and level'the plow, substantially as described,and for the purpose set forth.
